| 摘 要： | 为了验证利用GPS-R遥感技术反演植被生物量的可行性，分析了GPS反射信号反演植被生物量的原理与方法，通过试验利用干涉复合场数据（ICF）计算出信号反射率，利用已有文献拟合出的信号反射率与植被生物量之间的关系求出生物量，并与遥感技术结果进行了对比。试验结果表明：利用GPS-R遥感技术反演植被生物量是可行的，但是精度还需依靠时间反演模型；GNSS-R反演植被生物量对分析调查区域植被生长和碳排放情况具有重要意义。

| Abstract: | To verify the feasibility of using GPS-R technology to inverse vegetation biomass, the principle and method inversing vegetation biomass using GPS reflected signal were introduced.The paper performed an experiment to calculate the signal reflectivity using ICF.Using the relationship between the reflectance signal and vegetation biomass, the vegetation biomass was figured out and compared with the result of NDVI remote sensing.The results indicate that it is feasible to retrieve vegetation biomass using GPS-R remote sensing,which has great significance in vegetation plant and carbon emission investigation. |
